WebMay 24, 2024 · A half-life of 12-48 h is generally ideal for once daily dosing of oral drugs. If the half-life is too short, it may require more frequent dosing in order to maintain desired exposures and avoid unnecessarily high peak concentrations. This may pose challenges to achieving optimal efficacy, safety, and patient compliance. WebJun 7, 2024 · As a result, immediately following the initial bolus dose, drug concentrations will begin to decline. We frequently describe this decline in terms of half-life (the time required for drug concentration to decline by 50%). If our hypothetical drug has a half-life of three hours, we will observe a concentration of: 25 mg/L at three hours post-dose

The two main factors which affect drug half-life are volume of distribution and clearance; the formula for half-life is (t½ = 0.693 × Vd /CL). The 0.693 factor is in fact the logarithm of 2, which represents the fact that drug clearance typically … WebPeak and trough levels indicate drug levels in an individual’s body. A peak is the highest level of a medication in the blood, while a trough level indicates the lowest concentration. Troughs of medication concentration occur after the drug has been broken down and metabolized by the body. programmed i/o example
